I'm using ggmap to find locations. Some locations generates error. For example,
library(ggmap)
loc = 'Blue Grass Airport'
geocode(loc, output = c("more"))
results in
Error in data.frame(long_name = "Blue Grass Airport", short_name = "Blue Grass Airport", :
arguments imply differing number of rows: 1, 0
It's ok if I can't get results for some locations, but I'm trying to work on 100 locations in a list. So is there a way to get NA instead of error and keep things go on? E.g.,
library(ggmap)
loc = c('Blue Grass Airport', 'Boston MA', 'NYC')
geocode(loc, output = c("more"))
should generate
NA
Result for Boston
Result for New York City
You can make use of the R
tryCatch()
function to handle these errors gracefully:If you intend to loop over locations explicitly using a
for
loop or using anapply
function, thentryCatch()
should also come in handy.
